SHOE-LAST.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed May 29,1902. Serial No. 109,475.

To all whom it man) concern.-

Be it known that I, JOHN C. SoHELTER,-of Rochester, in thecounty of Monroe and State of New York, have invented certain new and useful Improvements in'Shoe-Lasts and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying crawings, forming a part of this spedficatlon, and to'the reference-numerals marked thereon.

My present invention relates to lasts, and

articularly to that class of lasts which embody the forward or toe section and the heelsection and my invention relates articularly to the construction of a suitab e hinge connection between these parts which will be strong, sim le in construction, and easily applied 1n suc a manner that as the arts are moved relatively to each other the ength of the last will be shortened, permitting its easy removal from the'shoe.

To these and other ends the invention consists in certain improvements in construction and combinations of parts, all as will be more fully described, the novel features being pointed out in the claims at the end of the specification. l i

In the drawings, Figure 1 is a longitudinal sectional view of the last, illustrating the application of a hinge constructed in accordance with my invention. Fig. 2 is a detached perspective view of the hinge and cooperat mg parts. Fig. 3 is a side elevation of the last, illustrating the operation of the hinge; and Fig. 4 is a cross-sectional view on the hne A A of Fig. 1.

Similar reference-numerals in the several figures indicatesimilar parts.

In illustrating the hinge I have shown it applied to a last consisting of the forward or toe section 1 and the rear or-heel section 2. At its u per side these parts are formed with incline" faces 3 and 4, respectivel y, forming a -V-shape notch, and at the bottom of the notch is a transversely-extendin curved recess arranged with its center in line with or below the plane of the face 4, so that a hooked shoulder or projection 5 is formed at the rear end of the. section 1. A last of this description is usually constructed in the first instance of a single piece of material, and the circular recess is formed therein by passing a V cutting-tool transversely through the last.

The V-shape notch is then formed by sawing along the lines indicating the faces 8 and 4,

" and to separate the heel and toe sections the parts are severed upon a line 6, which is preferably curved and arranged so that its upper end intersects the face 4 at a point in rear of the recess, leaving the shoulfler 5 upon the forward or toe section, as shown.

The hinge member or connecting-plate (illustrated in Fig. 2) consists of a base 7, preferably of sheet metal, havingitslower end 8 curved, as shown, and extending below the lower side of the base, so that when the latter is applied to the heel-secti on 2 of the last the portion 8 may be inserted into the circular recess in the section 1 by a relative lateral movement of the parts, when it will be engaged by the shoulder 5 to prevent the separation of the parts either vertically or longitudinally. To securely attach the hinge member to the face 4, I provide the base thereof with a downwardly-extending rib or portion, preferably formed by indenting the base transversely near its upper edge, as indicated at 9. The rib lies in a corresponding depression or channel provided in the face 4, and in this indentation is located a bar or head 10 of a T-shaped rivet, the shank 11 of which extends downwardly through the heel-section 2 and is secured by upsetting its lower end beneath a washer 12. Other means of attaching the hinge member or plate may be employed; but the arrangement 'of the depressed portion or rib 9 is desirable, as by its engagement with the face 4 the parts are securely held by the single rivet and the twisting of the parts by rough handling is entirely prevented. The depression also permits the aperture through which the rivet extends to pass downwardly and across the grain of the wood, so that when the rivet is secured the heel-section is strengthened rather than weakened by the rivet therein. To prevent a lateral movement of the two sections of the last, I secure the portion 8 of the hinge by means of a rivet 13 in the toe-section 1 of the last, which passes through an elongated aperture 14, formed in the hinge member, and to out its length also pass the rivet through the bar or bridge piece 15, and in'the lower side thereof are provided cut-out portions or recesses forming the central and end bearing points or feet, and between the latter are accommodated the convolutions of the coilform an even {)ressure on the hinge throughspring 16. If desired, a wear-plate 17 may be employed, curved to conform to part of the portion 8 and ada ted to lie beneath it. To secure the wear-p ate 17, I preferablyprovide it with an aperture, and the rivet 13, passing therethrough, securely positions it in the circular recess.

In order to support the sections of the last in the normal extended position, as shown in Fig. 1, I employ a spring 16, which is formed with the-two coils arranged upon opposite sides of a central rearwardly -extending loop 18, said coils being secured beneath the bridge-piece 15 with the loop 18 engaging the base 7' of the hinge, while the ends of the spring are extended upwardly and forwardly to engage the face 3 and are preferably provided with outwardly-projecting tips 19, which are engaged in suitable apertures. Various foms of springs may be used between the parts to hold the last normally in extended position; but the spring which I have shown and described is preferable, as the outer'ends are separated a sufficient distance to permit the loop to pass between theends when the parts of the last are turned, as shown in Fig. 3, and by inclosing the coils beneath the bridge-piece 15 it is impossible for the spring to become displaced. Further, the bridge-piece extending over the coils and not engaging therewith permits their free operation through all of the convolutions whenever the hinge is o erated.

The. hinge which I ave shown and described consists of but a single piece, which ma be easily formed from sheetmaterial, an while its construction may be changed without departing from the spirit of my invention the form I have-shown is preferable, as the last with which it is employed is easily formed and the hinge rigidly secured to one of the parts by a single fastening device, and its journal connection with the other portion being near one edge of the last permits the length of the latter to be decreased when the arts are moved toward each other, thus alowing it to be readily appliedto and removed from a shoe. Moreover, the shoulder 5 engaging. in rear of the portion 8 on the hinge member prevents the portions of the last from being separated by other than a relative lateral movement, which is prevented by the securing device or rivet 13.

I claim as my invention 1. In alast, the combination with a heel and a toe section, one of said sections having a recess open at the top and provided with a curved bottom, of a plate on the other section having a curved end bearing against the curved bottom of the recess in the first section to form a hinge connection therewith and means for preventing the lateral movement of one section relativel to the other, said sections being divided a ong a line terminating outside of said recess;
